ycitizen of the United States of America, re-

siding at New York, in the county of New York and State of New York, have invented new and useful Improvements in Bottle- Closures, of which the following is a` specification. .c j

This invention relates tobottle-closures.

The objects of the invention are to improve the construction of such devices; furthermore to increase their eliciency in o eration and to decrease the expenseatten ing their manufacture and application to a bott e.

With the foregoing and other objects in view, which will appear` as thedescription proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed as a practical embodiment thereof.

In the accompanying drawings, forming part of this'speclfication, Figure 1 is a side elevation, partly in section, of a bottle provided with a cap constructed in accordance with the present invention." Fig. 1a is a side view of the cap employed in the construction shown in Fig. 1. Fig. 2 is a similar view showing a slightly-modified construction. Fig. 2a is a side view of the capeinployed in the construction shown in Fig. 2. Fig. 3 is a vertical section of another modiiied construction. Fig. 4 is a view similar to Fig. 3 with the parts separated. Fig.5 is a side elevation showing the invention in connection with a jar. Fig. 6 is a vertical section of the construction-shown in Fig. 5.

Like reference-numerals indicate corresponding parts in the different figures of the drawings.

The reference-numeral 1 indicates a bottle or jar which may be of any suitable form, size, shape, and construction. Bottle 1 is formed adjacent to the up er end thereof with an annular rib or shoul erv 2. Extending upward from the rib or shoulder 2 is a plurality of separated s iral threads, such as 3 4. Eachof the threa s 3 4 is adapted to be engaged by an inward projection upon a ca suchas 5, which may be crim ed or roug cned around its periphery, as in icated at 6 in order to facilitate its application to and removal from the bottle. The inward projec by notching or stamping inward a portion of the lower edge thereof, as indicated at 7. Each of the notches 7 preferably is formed with an inclined upper `end, as indicated 'clearly in Figs. 1, 2, and 6, the incline of the up er end ofthe notch bein the same as the inc ine of the shoulder or t read `3 4, which said notch is intended to engage in appl in its to with'a depression, such as 8, and is provide interlorly with a disk, such as 9, of

tions on the cap 5 preferably are produced the cap to a bottle. The cap 5 is formed any suitable material, the disk 9 being adaptv ed to be forced closely a ainst the upper end of the bottle by means el the depresslon 8 in order to close said bottle in an air-tight manner.

The construction illustrated by Fig. 2 is exactly the same as that illustrated by Fig. 1,

except that the bottle is provided with two more closely-related separated spiral threads 10, and the cap 5 is formed with an additional number of notches 11, having inclined upper ends to enga e said threads. It will be apparent that t e invention can be carried out y usin two or in some cases even more separated t eads.

' It will be observed from Fiffsi and 2 that i the separated threads extend` u ward from the annular rib or shoulder 2. or this reason it is onl necessary to give the cap a partial revolution in order to lock it in position upon the bottle. Furthermore, it will be observed that when. the cap is reversely rotated thetotches will ride up the threads, so as to release the ca quickly from its engagement with the bott e.

inclusive, are practically the same as those or jar is rabbeted, as indicated at 12, to re- The constructions illustrated in Figs. 3 to 6,.

ceive an inner seal or disk, such as 13. The

disk 13 may be either flat, as indicated in Figs. 3 and 4, or dished, as indicated in Figs. 5 and 6. When a dished disk is employed, the depression 8 strikes against the dished portion of the disk so as to flatten the same and cause it to expand in diameter, so as to form an air-tight seal in the'upper end of the bottle or jar. j v.

lIt' is wellknown that in usin a jar or bottle having the ordinary form o single spiral thread it is necessary that the cap be also threaded. Furthermore, in applying the I n Y l; old form of threaded cap it is neeessary to give the same a plurality of revolutions in orer to apply it to the bottle. According to the present invention, the, expense and time consumed in forming v a cap with screwthleads is avoided, and a Great saving of time is effected in applying the cap after the contents of the jar or bottle have been inserted.

The improved bottle-closure of this'in? vention is strong, simple, durable, and inexpensive in construction, as well as thoroughly efficient in operation.

Changes in the recise embodiment of invention illustrate and described ma be made Within the sco e ofthe following clyaims without departing om the spirit of the invention or sacrificing any of its advantages.

It will be observed that in each instance each ca is provided with one or more inunche locking projections, said projections eing formed at the extreme lower ed e of' the cap, each projection having an inc ined upper wall and being minus a lower wall, the exterior recess formed in the ange of the cap by each projection opening at its lo/wer end t rough the edge of the cap. By this construction less resistance is encountered to the action of the die in forming the locking projections and less care is required in finish- 1ng the cap, as it is not necessary to take measures to prevent bulgign or outspreading of the metal, such as wou d be necessary in forming the projections wholly above the 'upper edge of the cap, in which action there would be a tendency of the metal below the lower end or base wall of the projection to bend outward on the inward punching of the metal by the die. Furthermore, the less resistance encountered in forming my improved construction of the projections minimizes fracture of the metal and reduces wastage from the formation of imperfect caps. Another advantage over a structure of the character referred to in bringing the projections as close down to the edge of the cap as possible which my constructlon secures 1s that the lower ends of the spiral threads may befarranged in closer contiguity to the shoulder 2, thus enabling the height of the neck portion above the shoulder on which said threads are formed to be decreased without decreasing the length of the threads and the degree of movement of the cap.

It will also be observed that the separated spiral threads connect at their lower ends with the shoulder 2. By this means stops are formed at vthe juncture of each thread with the shoulder to be engaged by the projections on the ca to limit the turning move ment of the cap ownward on the neck.y As a-result, the formation of spaces which will ermitl the projections to-ride beyond the ower ends of the threads is prevented, and liability of the projections becoming hung against the threads and mutilating or otherwise distortin the cap, so that it cannot be removed, is o viated. As the formation of the projections 11 directly at the lower edge ofthe cap allows the edge of the cap to come 7o walls of the projections against the shoulder 2, which thus reinforce said projections and prevent their distortion.

Having thus described the invention, what is claime as' new is- 1. A bottle vor jarhaving a rabbeted portion, a dished disk adapted to fit said rabbeted portion, and a cap adapted to flatten said dished disk to increase its diameter.

2. A bottle or jar having a rabbeted portion, a dished disk adapted to fit into said rabp beted portion, and a cap having a de ression in its end adapted to iiatten the dis ed disk to increasel its diameter.

3. A bottle or jar having a rabbeted portion, an annular rib, and a plurality of sepa-'f rated spiral threads extending upward from the rib, a dished disk fitted into the rab-v beted portion,. and a cap having a depression to flatten the dished disk and a plurality of IOO inclined notches in the lower edge thereof to form inward dpirojections to engage the sepaarated threa 4. A bottle or jar provided with an annular shoulder and a plurality of super osed separated threads connecting at their ibwer ends with said shoulder, in combination with a capv having 4 one or more inpunched rojectionsat its lower edge to engauge said t eads, said projections being provided with inclined upper walls having an angular arrangement with relation to the lower edge of the cap conforming to the langular arrangement of the threads with relation to the shoulder, whereby stops are provided at the 'unotion of the threads with the shoulder to imit the turning movement of the cap, the relative angular arrangement ofthe parts being such as to adapt the cap to be 'screwed down into close contact with the shoulder so that the inclined upper walls of the projections and basal edges o the inner walls thereof will res ectively gated neck having an annular'iribbr shoulder and' a plurality of superposed separated threads connecting at their lower ends with said shoulder, in combination with a cap having' one or more inpunched rjeetions at its lower ed e to engage said t eads, said proare provided at the 'unction of the threads with the shoulder to imit the turning movement of the cap, the relative angular movement of the parts being such as to adapt the cap to be screwed down into close Contact with .f the shoulder so that the inclined upper walls ofv the projections and basal edges of the inner Wal s thereof will respectively bear against the threads and shoulder and exert resisting pressures to prevent injury to the projections when the ca is screwed on.

6. A bott e or jar having a rabbeted ortion, and a pluralit of separated threa s, a dished disk ada te to fit said rabbeted portion, and a cap aving a depression to flatten said disk, and means toengage the separated threads.

In testimony whereof I affix my signature in presence of two Witnesses.
